Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s positioning can be adapted for consideration of different natural considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. Most modern rifle optics have around eleven parts which are found internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of scopes.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has determines where the reticle or crosshair lies in regard to the scopes zoom. It literally means the reticle is behind or before the magnifying lens of the scope. Picking the most suitable style of rifle scope depends on what form of shooting you anticipate doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) include the reticle before the magnifying lens. This causes the reticle to increase in size based on the amount of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards by using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are low
- Experienced shooters who have an idea for their aim point “hold over” and “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This induces the reticle to remain at the same dimensions in connection with the quantity of magnification being used. The outcome is that the reticle measurements adapt based upon the zoom chosen to shoot over lengthier distances given that the reticle markings represent distinct increments which change with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular varieties of optics are useful for:
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less space taken up by the larger size FFP reticle
Rifle Optic Zoom
The amount of scope zoom you require depends on the type of shooting you plan to do. Almost every kind of rifle scope provides some level of zoom. The amount of magnification a scope gives is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification level of the scope is the “power” of the opic. This implies what the shooter is observing through the scope is magnified times the power element of what can generally be seen by human eyes.
About Single Power Lens Optics
A single power rifle optic comes with a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate because it is fixed.
Variable Power Lens Glass Info
Variable power rifle scopes use variable power levels. The power change is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some recommended scope power settings and the distances where they can be efficiently used. Highly magnified rifle scope glass will not be as useful as lower powered glass given that too much zoom can be a negative aspect depending on your shooting distance. The exact same concept applies to extended ranges where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Lens Finishing for Rifle Glass
All contemporary rifle scope lenses are layered. There are different types and qualities of glass lens coverings. Lens finish can be an important aspect of a rifle’s setup when contemplating luxury rifle optics and scope units. The glass lenses are among the most crucial components of the glass considering they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens surface area as well as helps with anti glare from refracted light and color profiles.
Details on Lens Coatings – HD Versus ED
Some rifle scope suppliers even use “HD” or high-def lens coatings that use various processes, chemicals, polarizations, and components to extract numerous color ranges and viewable definition through the lens. This HD finishing is commonly used with increased density lens glass which drops light’s opportunity to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be visible over things with well defined outlines as light hits the object from certain angles.
Single Covering Versus Multi-Coating for Optics
Different optic lenses can likewise have different finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope company and the amount you spent for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has numerous treatments applied to them. If a lens gets multiple treatments, it can show that a maker is taking numerous actions to combat various natural elements like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally does not necessarily suggest the multi-coated lens is better than a single coated lens. Being “better” is dependent on the maker’s lens treatment technology and the quality of components used in constructing the rifle optic.
Hydrophobic Lens Coatings
Water on an optical lens does not support retaining a clear sight picture through an optic whatsoever. Lots of top of the line and premium scope makers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Scopes on Long Guns
Mounting options for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use throw levers which enable rifle shooters to quickly mount and dismount the scopes.
Hex Key Rifle Optic Ring Mounts
Basic, clamp-on style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This form of scope mount is ideal for rifles which are in need of a durable, rock solid mount which will not move despite just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a specialized scope setup on a reach out and touch someone scouting or tournament long gun which will hardly ever need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to stop the hex screw threads from backing out after they are mounted tightly in place. An example of these rings are the 30mm style from the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can wreck a day of shooting and your pricey optic by resulting in fogging and creating residue inside of the scope’s tube. Many optics protect against wetness from going into the scope tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for basic use rifles, unless you plan on taking your rifle aboard watercrafts and are worried about the optic still functioning if it is submerged in water and you can still recover the firearm.
Gas Purged Rifle Glass Tubes
Another element of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less affected by temperature level changes and pressure variations from the outside environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
